llvm-6502/include/llvm/Assembly/PrintModulePass.h
Chris Lattner b12914bfc0 'Pass' should now not be derived from by clients. Instead, they should derive
from ModulePass.  Instead of implementing Pass::run, then should implement
ModulePass::runOnModule.

// simply prints out the entire module when it is executed. The
// PrintFunctionPass class is designed to be pipelined with other
// FunctionPass's, and prints out the functions of the class as they are
